i am currently running a single stage setup now,an am still learning about it. what does the two stage exactly do? dont know thats why im asking, i would think would it not just b e easier to put in a bigger jet on a single stage, maybe thats not the case? what is needed to add this, i am using a hobbs switch now. when the second stage comes on does that mean both solenoids r spraying? enlighten me here
